'Iihe lower. roll I. 1 of. this? wringer ispreferably of smaller diameter than the upper r011 4-to ob? tain a wringing combination wherein the large roll provides a greater squeezing area of contact in combination with a Smaller roll better adapted for handling buttons, etc., or small gathered or 'folded portions of the clothing as the same are passed through the wringer. Furthermore, the

ment of the lower roll which can be accomplished wringer structure itself.

This lower roll I1 is carried upon the usual shaft l8 and the latter projects from the opposite ends of the roll and'seats within the saddle bearings 9 and 29 as best seen in Figs. 3 and 4. Bearings I9 and 29 are secured by means of pins 2| and 22 respectively to the guide yokes 23 and 24 while the latter are slideably carried within the vertical channels 25 and 26 secured in any convenient manner to the wringer frame.

The spring tensioned link mechanisms 21 and 28 are connected with the bearing units |9 and respectively to normally urge the lower roll |1 into operative pressing contact with the upper roll 4 under normal conditions of operation of the wringer. These-mechanisms 21 and 28 are substantial duplicates and function in the same capacity at each end of the wringer. For this reason the explanation will be directed to the link mechanism 21 best illustrated in Figs. 3 and 4. The guide yoke 23 for the bearing I9 is provided with pairs of ears 29 and 39 oppositely relatedat the upper portion of the slideable bearing structure. Bell cranks 3| and 32 are connected with the ears 29 and 30 by means of the pivot pins 33 and 34' respectively, and such bell cranks 3| and 32 are further pivotally supported upon the pins 35 and 36 carried by the swingable links 31 and'36 that are pivotally supported at 39 and 49 respectively from suitable bearing brackets 4| and 42 connected with the main housing of the wringer. Thus, the pivotal connections 35 and 36 produce roving pivotal points for the bell cranks 3| and 32 to permit fulcruming of the latter links about these pivot points while the pivot pins 33 and 34 of the guide yoke 23 can be vertically moved in a straight line to shift the roll H in a vertical path by means of the shaft l8.

A pair of links 43 and 44 are pivotally connected by means of the pins 45 and 46 respectively to the opposite ends of a common link 41, and

the latter is pivotally connected at 48 to a bracket 49 suitably connected with the bearing guide channel 25. Links 43 and 44 have their free ends pivotally connected by means of the pins 59 and 7 5| to the ends of the bell crank levers 3| and 32.

Any suitable spring or tensioning means may be interposed into the link mechanism described and between the latter and a release means to entirely relieve the spring of any tension and at the same time relieve any tension that may be transferred through the link mechanism to the lower roll H of the wringer. In the present construction'a spring 52 has one end thereof connected with a lug 53 forming an'integral portion of the link 43, while the other end of the spring 52 is looped about a pin 54 carried by the semicircular link 55. This link 55 is pivotally connected at 56 to an arm 51 forming an integral portionof the spring release shaft 58 extending substantially the length of the wringer structure and supported in bearings 59 and 60 connected with the main wringer housing as illustrated in Fig. 1.

' lazy tongs.

With this spring structure it is evident that the tension of the spring istransmitted through the link 43 to the common link 41 pivoted at 48 and from the common link 41 to the link 44 tending to produce clockwise rotation of the link 41 thereby causing link 43 and 44 to urge the pivotal points 50 and 5| inwardly toward the longitudinal vertical median plane of the wringer rolls. This action urges the bell cranks 3| and 32 in a direction for counter-clockwise and clockwise rotation respectively causing the pivotal connections 33 and 34- to be urged upwardly, the link mechanism functioning substantially in the manner of From this action the guide yoke 23 holds the bearing I9 upwardly under the spring tension thereby holding the lower roll l1 in operative wringing contact with the upper roll 4. Furthermore, as long as the shaft 58 and the connected link 55 are maintained in the particular position illustrated in Fig. 3, the spring 52 is in stretched condition producing the proper tension that is transmitted through the link mechanism to the lower roll in the manner explained.

Since the same description will apply to the corresponding link mechanism 28 incorporated in the outer end of the wringer structure, no further explanation will be tendered excepting to say that the wringer mechanism 28 has been given the same reference characters with a attached such as 33a,'34a, 35a, for example, to indicate like parts.

A manual release mechanism including coop-v erative latch mechanismcoacting with the release shaft 58 has been introduced to provide a trigger release means for instantly relieving the tension of the springs 52 and 52a to permit the lower wringer roll H to part freely from opera-' tive contact with the upper wringer roll 4. The manual release mechanism herein employed is best illustrated in Figs. 2 and 3 and comprises a parallelogram framework. This framework comprises two longitudinally disposed shafts or operating rods 6| and 62 pivoted on extensions 63- and 64 forming a portion of the channels 24 and 25 for guiding the lower roll bearings I9 and 28. Connected with the pivotally supported rods 6| and 62 are the U-shaped release bars 65 and 66 having vertical legs 61 and 68 supporting release bars 69 and 1|] arranged to flank the opposite sides of the upper wringer roll 4 and to extend longitudinally and beyond the ends of such upper wringer roll. The vertical legs 61 and 68 are disposed in parallel positions and are connected by links 1| and 12 having pivot pins 13 and 14 respectively located to'form a parallelogram when considered with the axial positions of the rockable rods 6| and 62.

This entire vertical framework, including the longitudinally carried release bars 69 and 18 is normally maintained in the vertical position 11- lustrated in Fig. 3 by means of the stabilizin unit 15. This positioning means 15 comprises a rod 16 having a flat surfaced head 11 which 'bears directly against a corresponding flat surface on a block 18 and the latter is secured to the rod 6| in any desirable manner. The rod 16 extends through an opening 19 in any suitable supporting member which in the present construction comprises a non-rotatable supporting shaft mounted on the wringer housing. A spring 8| is interposed between the head 11 of the rod 16 and the supporting shaft 89 to continually urge the two flat coacting surfaces of the head 11 and the block 18 into contact. Therefore, so long as these surfaces are in direct contact illustrated in Fig. 3

By the use of the gears 90 and 9| it is possible to provide a handle reset means that may be of fair size inasmuch as the same can be stored in inactive position beneath the wringer. The result is that such a handle is hand operated to move in a horizontal plane disposed beneath the wringer structure. As described, the handle is free under normal conditions but connectible to reset the spring tensioning means of the wringer. It is to be understood that other equivalent structures may be substituted for those specifically described to perform the particular functions of the mechanisms embodied in the wringer of the present invention.
